So I see that were going to be getting a ground swell this weekend in the 12 sec range. What I don't get is where is the wave? How does a 12 sec ground swell produce ankle slappers? Can someone please explain!
what location are you looking at? The swell period term "ground swell" just refers to the swell period time and nothing more. So what you are looking at is a very small 12 second wave. Look at the swell plots for the exact swell height, swell period, and swell direction.
Thanks for clearing that up. For some reason I always associated a 12 sec period ground swell with some what decent waves, considering the wind as always. Most places that get 12 sec or better g-swell get pumping surf. I guess here on the east coast 12 sec period still produces crappy surf. Thanks for the info you guys sre always on it!!!!!!!!!!!!!!!!!!
There is always a swell height and period combination. A 1ft swell @ 12 seconds is nothing. Where as a 4ft swell @ 12 seconds has much more energy as compared to a 4ft swell @ 6 seconds. The 4ft @ 6secs is prob like waist high (maybe a slighltly bigger peak), where the 4ft @ 12 seconds could be like chest - head with longer lines and generally much more power behind the wave.
